Elements that are in the same group on the periodic table have similar ionization energies. That's the energy needed to remove an electron.
Here’s why they are similar:
They Have the Same Number of Valence Electrons: These are the electrons that are found in the outer shell. Because they have the same amount, it affects how tightly these electrons are held.
Atomic Size Gets Bigger as You Go Down a Group: Even though the positive charge in the nucleus increases as you go down, the outer electrons are farther away. This distance makes it easier to take those electrons away.
These reasons can make it hard to predict the ionization energies of elements.
However, by understanding how electron shielding and atomic size work, we can see some patterns.
With continuous study and practice, anyone can get better at this!
